And yet

> I wanted to inform you that the Director of the Central Intelligence Agency (CIA) directed in August 2013 that the agency make no operational use of vaccination programs, which includes vaccination workers. Similarly, the Agency will not seek to obtain or exploit DNA or other genetic material acquired through such programs. This CIA policy applies worldwide and to U.S. and non-U.S. persons alike.

The CIA themselves recognizes such an approach as being bad overall.
